Revna jasper, with its distinctively striated green and white appearance, was discovered in the late 18th century in the Ural Mountains and seems to be particularly associated with the Kolyvan workshops-Mount Revna was about 28 miles away. A number of pieces executed in Revna Jasper in the Kolyvan workshops are in the Hermitage Museum, St. Petersburg, including a bowl of astonishing size, measuring over 13 feet in diameter, which took over fourteen years to create, from 1829-1843 (see A. Cheneviere, Russian Furniture The Golden Age 1780-1840, London, 1988, pp. 259-61 and 274-5, and E. Efimova, Russian Stoneware in the Hermitage Museum, Leningrad, 1961, p. 32 and figs. 68-9 and 73).
